This invention relates to aldevice for applying anti-skidding media to the tires of motor vehicles in accordance with the method described in my co-pending application Ser. No. 621,759,

which matured into Patent 1,943,917, January 16, 1934, according to which rubber tires of motor vehicles are prevented from vskidding on slippery roads by applying to them, during or prior to driving, a requisite quantity of an anti-skid- 'cling medium which consists of a solution of resin in alcohol or the like separated out as a viscous, sticky mass by dilution with water and which is distributed by pipings from a container near the drivers seat over the treads of the wheels.

The device according to the invention employs a plurality of cylinders of equal size as measuring vessels for applying the necessary amount of anti-skidding medium 4to the various tires by means of spraying nozzles.

By way of example, one embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a view of the device;

Fig. 2, a'section of Fig. 3 on the line A-A;

Fig. 3, a section of Fig. 1 on the line D-fD;

Fig. 4, a section of Fig. 2 on the line B-B;

Fig. 5, a .section of Fig. 2 on the line CC; and

Fig. 6, a sectionalvview of the spraying nozzle on an enlarged scale. v l

Referring to the drawings, the casing 1 contains the connecting rod 2 guided at one end in the holding disc 3 and secured with its other end to the disc 5 which serves as carrier for the pistons 6. Thedisc 5 may be provided on its back with two' spring bolts 7 surrounded by the helical springs 12 and guided in the bushings 17 which are disposed in the holding disc 3. The pistons 6 t into the measuring cylinders 8 and if withdrawn therefrom against the action of the helical springs 12 by means of the handle 4 rotatable about the shaft 18, a vacuum will be produced in the cylinders 8Y and anti-skidding liquid will be drawn in from the reservoir 9 through the filling tube 10 and the spring valve 16,Y the liquid passing from the filling tube 10 through the connecting ducts 11 into the measuring cylinders 8 until the latter are lled. When the handle 4 is released, it will return to its original position, the springs 12 will be relieved from tension and drive forward the disc 5 and the pistons 6 attached thereto which will enter the i measuring cylinders 8 and press the anti-skidding liquid contained therein into the pipings 19 provided at their ends with the spraying nozzles 5 13'. 'I'he liquid is then pressed out of the nozzles 13 and equally sprayed over the tires. 'In front of their outlet openings the nozzles 13 are each tted with a. check valve 14v for preventing the discharge of liquid when the device is not in operation as well as the entrance of moisture from without whereby the adhesive mass would be separated within the device. To keep the nozzle aperture open, thecheck valve 14 is provided with a needle l5 which passes through a corresponding opening in the casing 20 and 65 pushes through the mouth of the nozzle when the spraying device is released. The spring valve 16 in the filling tube 10 opens as soon as the pistons 6 are drawn back and a vacuum is produced in the measuring cylinders vI0 8 so as to permit the anti-skidding liquid to now from the reservoir 9 into the cylinders 8. When l the cylinders have been filled the spring valve i 16 closes automatically and thus prevents pres-f Isure from reaching the reservoir 9 through the 75 tube 10 during the `spraying operations.

I claim:-

1. A device for applying anu-skidding media -to the tires of motor vehicles, comprising a plurality of cylinders of equal size to serve as measuring vessels for anti-skidding medium to be supplied to tires of the motor vehicle and means for ejecting substantially equal'amounts of antiskidding medium from said cylinders.

2. A device for l,applying anti-skidding `media to the tires of motor vehicles, characterized in that a plurality of equal cylinders serving as measuring vessels areconnected with pistons for ejecting the anti-skidding medium and with pipings terminating in nozzles through which the anti-skidding medium is conducted and sprayed in atomized condition on the tires.

3. A device for applying anti-skidding media to the tires of motor vehicles, characterized in that the device comprises a plurality of cylin- 95 ders for receiving and squirting out the antiskidding medium through respective pipings opening into nozzles, said device being so dimensioned as to squirt an equal amount of antiskidding medium on the tires at each operation.

4. A device for applying anti-skidding media to the tires of motor vehicles, characterized in that the device comprises a plurality of cylinders, a reservoir, and aV spring valve disposed between the cylinders and the reservoir and adapted to open on the withdrawal of the pistons guided in the cylinders, and to close automati` cally as soon as the cylinders are lled with antiskidding medium from the reservoir.

5. A device for applying anti-slipping media to the tires of motor vehicles, comprising a plurality of pumps, a reservoir for supplying antislippingmedia to said pumps, conduit means connecting .said reservoir and said pumps, conduit means connected with the discharge part of each of said pumps and adapted to apply antislipping media" to said pumps, conduit means hicle, said pumps being so dimensioned that approximately equal quantities of anti-slipping media are discharged from said nozzles when the pumps are operated.

- 6. A device for applying anti-slipping media to the tiresof motor vehicles, comprising a plurality of pumps, a reservoir for supplying antislipping media to said pumps, means for deliverin'g anti-slipping media from said reservoir kto said pumps, for applying anti-slipping media upon the tires of a motor Vehicle from the discharge part of said pumps, means for operating said pumps l substantially simultaneously, and said pumps 'being so dimensioned that approximately equal quantities of anti-slipping media are discharged upon the tires when the pumps are operated.

'7. A device for applying anti-slipping media to the tires of motor vehicles comprising a plurality of pumps, including a pressure chamber and means to develop pressure therein, the said pumps having such dimensions that approximately equal quantities of anti-slipping media are delivered from said pumps upon each delivery stroke of the pumps, means for delivering anti-slipping media from each of said pumps to the tires of a motor vehicle, a reservoir for supplying'anti-slipping media to said pumps, means for delivering anti-slipping media from said reservoir to said pumps and means for operating said pumps simultaneously to apply anti-slipping media. substantially simultaneously and in substantially equal amounts to the tires of the motor vehicle.
